    Pentru cei pasionati si cu un pic de expertiza in radio-electronica care nu au la indemana filtrele ceramice necesare ingustarii benzii IF din aparate dar care doresc obtinerea de selectivitate crescuta in cazuri extreme, reamintesc solutia sugerata cu multi ani buni in urma dar care a trecut nebagata in seama de catre ageamii, din motive lesne de inteles.


    Iata un mic DEMO cu receptia RR Actualitati din Vacareni in Bucuresti folosind un SDR pt demodularea frecventei intermediare FM (10.7 MHz) extrasa dintr-un receptor clasic stationar



    Receptie permanenta in Bucuresti cu fadingul de rigoare ...

    Spre disperarea profanilor

    Bonus

    Test - RR Iasi - Pietrarie in Bucuresti prin aceeasi metoda descrisa anterior



    Receptie relativ permanenta in Bucuresti cu fadingul de rigoare ...

    Spre disperarea si apoplexia profanilor ...

      Transmisie DRM in US, 15110 KHZ, radio Kuwait, 250 KW. Se vede pe spectru forma specifica a semnalului DRM, diferentiat fata de semnalele AM. Din pacate, DRM-ul este un tip de transmisie care nu a prins deocamdata, poate doar in India, experimentele dureaza de multa vreme dar fara prea mult succes. RRI are transmisii digitale in SW, dar limitate la 30 de minute in engleza, franceza, spaniola, chineza și cu o putere de 90 KW

                              completare (izolat emitatoare BG-Ruse/din pacate BG-Shumen-Venets este chiar in spatele antenei orientata pe culoarul costila-valea prahovei),
                              nimic din brasov...nimic de pe vf. harghita, in schimb intra Cluj-feleacul (fading/uneori stereo) si Focsaniul (Digi FM care sigur au o putere mult peste cea admisa legal) pe frecventa pe care cautam minisat predeal
